Correct Answer: B

Rationale: DiGeorge syndrome is caused by a congenital lack of thymic tissue, which plays a crucial role in T cell development and maturation, leading to immune deficiency. Choice A is incorrect because DiGeorge syndrome primarily affects T cells, not B cells. Choice C is incorrect as it is too broad and not specific to the thymus. Choice D is incorrect as selective IgG deficiency is a different condition unrelated to DiGeorge syndrome.

Correct Answer: D

Rationale: The primary reason for prescribing testosterone therapy for osteoporosis in men is to restore testosterone levels, not specifically to increase bone density. Testosterone plays a crucial role in maintaining bone density, so by restoring testosterone levels, it indirectly helps in maintaining bone density. Choices A and B are partially correct but do not address the primary reason for testosterone therapy in this context. Choice C is incorrect as the main focus of testosterone therapy in osteoporosis treatment is not related to enhancing sexual performance.

Correct Answer: A

Rationale: The correct factors that contribute to an individual's ability to adapt to stress are age, socioeconomic status, and gender. Age can influence coping mechanisms and resilience. Socioeconomic status can impact access to resources and support systems. Gender differences can also play a role in how individuals experience and manage stress. Ethnicity, while important in other contexts, is not directly mentioned in the provided rationale and is not one of the factors listed as contributing to an individual's ability to adapt to stress.

Correct Answer: C

Rationale: The correct answer is C because limiting fluid intake is not recommended for chronic bronchitis. Hydration is essential as it helps thin mucus, making it easier to clear from the airways. Choices A, B, and D are all correct statements for managing chronic bronchitis. Avoiding exposure to smoke, pollutants, and irritants can help reduce respiratory symptoms and exacerbations. Using the inhaler regularly, even in the absence of symptoms, is crucial for controlling inflammation and maintaining airway function.

Correct Answer: A

Rationale: The correct answer is A: Cerebral cortex. The cerebral cortex, particularly the motor cortex, is responsible for the voluntary control of precise movements such as turning a page. The cerebral cortex plays a crucial role in the highest level of control of motor functions, including those of the arm and hand. Choice B, Basal ganglia, is more involved in motor planning and coordination, while choice C, Brainstem, is responsible for basic life functions and reflexes. Choice D, Cerebellum, is primarily involved in coordination, precision, and accurate timing of movements, rather than the highest level of control for specific actions like page-turning.
